The film is in German - with some scenes in English - and the film is subtitled in English. It's shot in highly atmospheric black and white and, while it does expand on the story, on the whole it's quite faithful to Lovecraft. Creepy retro feel!

One of the oldest known amateur adaptations of an H.P. Lovecraft story. The strange story of the demise of two young students, a forgotten graveyard and the cosmic horror deep below! Shot in the summer of 1987 with a home VHS tape deck. Sanity-blasting!
